SPECIFICATION forming' part of Letters Patent No. 476,542, dated J' une 7, 1.892.

Application led August 21. 1891. Serial No. 403,280. (No specimens.)

To all whom t may concern:

Bc it known thatl, JOHANN HEINRICH KLEB, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Artificial Stone; and I do hereby declare the following to bea full, clear, and exact description of the invention', such as will enable others skilled in the art to which 1o it appertains tomake and use the same, reference being had to the accompanyingdrawing, and to letters of reference marked thereon, which forms a part of this specification.

The present invention has reference to an x5 improved artificial stone; and it consists in such stone made from a suitable mixture of coke or cinders, shell, cement, and gypsum, properly mixed with water and molded in forms into any desired shape.

The article itself is illustrated in the accompanying drawing, in which a stone made from this material is represented in perspective.

The method of producing thisartilicial stone is as follows: C ke or cinders are mixed with a desirable qu'antiiy 0I small pieces of shell,

preferably ovster or clim; hs, and mixed with a suita e quantity o cement and U sum to which water has b eenmadded.

A3o soit mixture is then frced'into suitable molds or otherwise formed `into any desirable shape and allowed to dry. In this manner a cheap artificial stone is obtained which is much lighter than ordinary stone and which, when placed in water, will not dissolve nor will it attract moisture.

These stones can be used as pavements or as cellar-floors, in which case they are placed side by side and united.by means of cement 4o or in any other well-known manner.

These stonespwing to their light weight, are of great ntilityin the erection of inside walls in buildings, in which case the stones are placed upon each other in the manner of ordinary bricks, being united by means of Inortar or cement. 'Phe exposed surfaces of the wall made in this manuel' are then treated with the usual coating of plaster. A solid wall is thus the result, which will attract no moisture and into whjgmilsecam be driven, and iu whichlfr narywdihiihsto which the plaster is usually attached are dispensed with. These walls are of great beneiit in case of tire, as there is no possible danger of the dames eating their way through the same, asin the walls of the usual construction, in which joists'and laths are used. These walls are very light, and, owing to the fact that they are solid,will sustain greater weights than the walls that are hollow. when provided with plaster have the usual appearance and are of cheaper construction, making a good sanitary wall.

These walls.

Having thus described my invention, what JOHANN HEINRICH KLEl-l.
